Clean Up Rusty Cast Iron with Coca-Cola (and Other Chemistry Hacks)

This video from the American Chemical Society explains the science behind several life hacks, such as using salt to fix bitter coffee, and introduces us to a new one: easily getting the rust off of cast iron with a little bit of Coke.

Coke, the video reveals, contains phosphoric acid, which is used industrially as a rust and tarnish remover. It makes the rust easier to remove. So if you ever accidentally leave your cast iron pan covered in water, just grab a bottle of Coke and get your cast iron looking brand new again (after you season the pan, that is).

Thank you, chemists.
